In talking about the Mets’ rotation plans general manager Sandy Alderson categorized Johan Santana as a “question mark” and told Adam Rubin of ESPN New York that the former Cy Young winner “might not be” ready for Opening Day.

Santana planned to return from shoulder surgery to pitch for the Mets down the stretch, but suffered various setbacks along the way and never threw a pitch in the majors.

Opening Day would be more than 18 months after his surgery and Alderson did say that “we think he’s going to be ready.”

Blash, 28, was acquired by the Yankees from the Padres back in December in the Chase Headley trade. In trading Blash to the Angels, the Yankees were able to free up a spot on the 40-man roster for Brandon Drury, the infielder they acquired as part of a three-team trade with the Diamondbacks and Rays on Tuesday.

Over parts of two seasons in the majors, Blash has hit an underwhelming .200/.323/.336 in 279 plate appearances. He will try to play his way into a bench role for the Angels this spring.
